Sorry for the non-descriptive bug title in advance, I'm not sure which parts of
the logs are worth a bug report, but I'm moderately sure that something in here
deserves a bug filed.
My machine is a Lenovo P50 with:
VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M2000M] (rev
a2)
And mesa version 17.1.8
I connected an external monitor to the HDMI port, and I got black screens for a
few retries.
On an unrelated (maybe not so unrelated?) note, I get reproducible FAULTs on
startup, regardless of any monitor attached or not I believe. I also got some
others on today's log, but that may be just related to the problem above. The
first two lines below repro even without an external monitor:

Happy to help providing more information, testing, or even trying to contribute
a fix (with some guidance ideally, since I know nothing about the driver's code
:P).
Thanks a lot in advance.</pre>
